Waxing Gibbous on . The illuminated surface of the moon is 76% and growing larger. The lunar cycle is 10 days young.
The moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Main moon phases of the following lunar cycle.
Moon is passing about ∠12° of ♐ Sagittarius tropical zodiac sector.
Previous main lunar phase is the First Quarter before 2 days on 30 July 2017 at 15:23.
Next Full Moon is the Sturgeon Moon of August 2017 after 5 days on 7 August 2017 at 18:11.
There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.
Lunar disc appears visually 6.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1768" and ∠1891".
The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 217 of Meeus index or 1170 from Brown series.
The length of this lunation is 29 days, 8 hours and 45 minutes and it is 2 hours and 15 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).
The length of the current synodic month is 3 hours and 59 minutes shorter than the mean synodic month length. It is 2 hours and 10 minutes longer compared to 21st century's shortest synodic month length.
The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠27.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠49.5°.
Moon is at apogee at 17:55 about 12 days since last perigee on 21 July 2017 at 17:09 in ♊ Gemini the lunar orbit is going to narrow while the Moon is moving towards the Earth over the upcoming 16 days until point of next perigee on 18 August 2017 at 13:14 in ♋ Cancer.
This apogee Moon is 405 026 km (251 671 mi) away from Earth. It is 382 km further than the mean apogee distance, but it is still 1 683 km closer than the farthest apogee of 21st century.
8 days after ascending node on 25 July 2017 at 00:46 in ♍ Virgo the Moon is positioned north of the ecliptic over the following 5 days until the lunar crosses the ecliptic again from North to South in descending node on 8 August 2017 at 10:56 in ♒ Aquarius.
11 days since the last northern standstill on 21 July 2017 at 22:11 in ♋ Cancer when the Moon has reached North declination of ∠19.413° the lunar orbit is extending southward over the next 2 days to face maximum declination of ∠-19.393° at the point of next southern standstill on 4 August 2017 at 18:17 in ♑ Capricorn.
8 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the beginning to the first part of the lunar cycle.
In 5 days on 7 August 2017 at 18:11 in ♒ Aquarius the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
